MAGAZINE PENCIL.

Specification of Letters Patent.

Patented Apr. 4, 1922.

Application led January 13, 1921. Serial No. 436,875.

To all 'Loh-0m z't may concern.'

Be it known thatl I, MARX FINs'roN'n, a citizen of the United States of America,- residing at Brooklyn, Kings County, State ofvNew York, have invented certain new and useful Improvements in Magazine Pencils, of'whioh the following is a full, clear, and exact-description.

This invention relates to improvements in magazine pencils, one of the objects being to provide a pencil of this nature that can be cheaply manufactured, and which will at the same time be substantial in construction.

To carry out my invention, l have designed a pencil, the partsof which canI be stamped out by suitable dies and a press,

'binding elements and soldering being dispensed with.

l will now describe my invention in detail, the'novel features of which I will nallyclaim, reference being had to the accompanying drawing, wherein Fig. 1 is a longitudinal sectionalview of my improved pencil;

F ig. 2 is an enlarged cross sectional view/ lle section being taken on a line 2 2 in Fig. 3 is a similar view, the section being taken on a line 3--3 in Fig. l;

Fig. 4 is a cross-sectional View, .illustrating the barrel of the pencil and the follower casing.; y

Fig. 5 .is a detail View, in elevation, partly in section, of the follower casing;

Fig. d is a detail View, broken away, of the lead screw;

Fig. 47 is a diagrammatic view, illustrating the follower and lead-screw assembled;

Fig. 8 is an end view of the follower, looking from the right in F ig. 7;'

Fig. 9 isa top plan viewvof the follower;

1() is an enlarged fragmentary sectional View, illustrating the manner of connecting the follower and' push pin carried thereby; and

i ig. 11 is a top plan View thereof. is herein constructed, my improved pencil consistsof. a barrel member 12 carryingv a removable nozzle section 13 through Whlch the tubular extension 14 of a casing 15 projects. llille casing table' cap orplug member 2O located at one 15V slidably supports afollower 16 carrying a pin 17, 'which is operend of the barrel 12, as shown in Fig. 1. When cap or plug 20 is rotated, lead-screw 18 will also be rotated, thereby operating the follower 16 longitudinally of the casing 15. The casing 15 is made up of two members 21 and 22 (in this` instance) held together by a ring 23-which is slipped over the cylindrical portion ofthe assembled casing, which is made up of the semi-circular portions 24 and 25 of the casing-members 21 and 22.

The binding ring 23 may be forced into position or spot-soldered after having been slipped into place. The ring 23 will, aft-er the casing 15 hasbeen placed in the barrel 12, serve as a back stop for reserve leads 26 (see Fig. 1) placed in the space between the cylindrlcal portion 'of the casing 15 and barrel 12. The nozzle 13 serves as a closure for the adj acent endof the barrel 12. Leads can be removed from the magazine'portion of the pencil after the nozzle 13 has been removed. The lead screw 18 consists of a lstrip of iiatmetal twisted to form spirals 18, said strip at one end being flat "as indicated by 19 to engage the cap or rotatable plug20. The end 19 of the strip will be molded into said plug or cap. Thev spiral portion of the lead screw engages a slot 27 in the upturned end 28 of the Vfollower 16 through which it passes, as can be seen in llig. 'l'. Hence, when the cap or plug 2O is rotated, the follower 16 willbe moved 1011-' gitudinally of' the casing 15 by the lead screw 18. y

The follower 16 is formed out of thin metal by suitable dies and theend plate 28 will be of such dimensions as to slidably en gage the interior of the casing ,15. .'lheend plate will be preferably made square, likewise' the body portion 29 of the casing 15;

hence the follower 'will not turn or rotate about the axis of said casing after it has lby dotted lines in Fig. '5. lNlieni the casing is inserted in the barrel andv forced home, the spread apart members of the body por'- tion will be brought together. As said members will be under tension, as the resultofl efore having been 'spread apart, the corners 30 will tightly grip the barrel of the pencil and prevent the casing from moving longitudinally of said barrel. The casing 15 may be inserted through either end of the barrel. The cap of plug 20 is reduced at 30 and provided wit-h an annular groove 31 in said reduced portion. After the casing 15 has been inserted, also the follower 16 and its lead-screw 18, to which plug 20 is attached, and after the reduced portion of thelug has been inserted in the adjacent end ol:P the barrel, the wall of the barrel will be forced inwardl as at 32 to engage thev groove 31; hence, the cap or plug will be held against removal from said barrel,.but at the same time will be rotatable, in order that the follower 16 can be manipulated. The follower 16 carriesv the push pin 17, which is preferably provided with a head 33. The pin 17 is held by the tubular end projection 34 on the follower body portion 16 and is held in sition by means of a recess 35 which the ead 33 enga s. rWhen the follower 16 is stamped out, e portion thereof from which the tubular end member 34 is formed will be approximately fiat or at least not 'wholly formed, nor will the recess 35 exist. After the pin 17 has been placed in position, the material adjacent the shank of the pin will be turned up and over to envelop the said shank adjacent its head 33. After this operation, the wall of .the follower will be forced inwardly whereby the said recess 35 will be formed. which 1n turn will be engaged by the head 33. By this means, the pin 17 will be held 'll'the follower without resorting to solder.

e end plate 28 will be an integral part of the follower, as isevident.

It will be seen that the casing is reduced in diameter throughout a portion thereof to provide a magazine for reserve leads, the remainder of the casing being arranged to grithe barrel of the pencil, as can be seen 1n 1g. 1.

It will be evident thatthe' casing 15`and follower ,16 are made out of thin metal suit-l ably formed by dies, and that the lead-screw .is made out of thin strip metal twisted to form a lurality of spirals to form a thread. The tu ular extension 14 ispreferablysecured to the casing members 21 and 22 by solder. The lead point will be placed in the tubular extension or lead carrier 14 and projected forwardly, or out of the carrier, by

the pin 17 when the follower 16 is forced forwardly b the lead screw 18. A -The barre 12 and nozzle section 13 will lbe made referably out of vulcanized rubber and aped to give the device the ap Eearance off a fountain pen. It will be seen referring to Figs. 3 and 7 thatthe follower 16 is of channel formation so as ,tov

behind the `head 33 asat 36,

deref Jersey, .1 921 receive the lead screw 18 after through the end wall 28. The follower will rest within the cylindrical portion of the it has passed casing 15 and be guided thereby. The end within same, a lead carrier supported by the` casing at one end thereof, a follower within the casing, a portion of said casing being of angular formation and arranged to grip the wal of said barrel, a follower within the casing,za push pin carried thereby, operable longitudinallyv of the lead carrier, a lead screw engaglng said follower, and means carried by the barrel to operate the lead screw.

2.. In a pencil, a barrelmember, a casing vwithin same consisting 'of a plurality` of spaced apart connected members, said members `at one end being under tension and tending to springoutwardly to grip the barrel, a lead carrier supported by the casing and projectin from one end thereof, a follower w1thin t e casing, a pin carried by the follower and o rable longitudinally of the lead carrier, a ead screw engaging the follower, and means associated with the barrel to operate the lead screw. l 3. In a pencil, a casing member for insertion within abarrel consisting of a plurality of separate channeled members, and means to bind said members together.

4. In a pencil, a casing member for insertion within a barrel consisting of a plurality of separate channeled members arranged to be spread apart at one end before being inserted into a barrel, whereby said members will exert 'pressure upon said barrel after the casing has been forced into position within-a barrel and the said members compressed and means to connect said members.

5. In a pencil, a casing member for inserpressed, means to connect the channeled members andv a lead carrier supported by the casing.
